First up a weather report to get us through the week for planning on our season extension:

There may be a day or two in this weather forecast to get inside the season extension to take a look at the crops. If it gets warm on a day, like 45 to 50 degrees at least, then you can pop the top with your students to see how the plants are doing. Make sure to cover up tightly when done.

Looking a little further ahead, it is supposed to stay close to normal temperatures through February with a larger chance of increased precipitation.

There should be enough precipitation that the crops under the row cover will not need watered.

Outside in the raised beds:

I have been getting questions about what can still be planted outside.  We are likely done with planting in the raised beds. (See Below for a potential!)  Many folks have stated that they did not get good germination.  The warmer than normal weather made germination tricky unless the beds were watered daily until sprouting.  The heavy rain we had the other day may cause some delayed germination under cover that we will find when we are able to pop off the covers.  Make sure that when we get to the cold weather you do not uncover your beds on a cold day so that you do not shock your seedlings.  It should be above 45 degrees minimum to pop the top and it is better done around the middle of the day so you can re-cover, and build heat back up for the overnight lows. I do not see many good chances in this weather forecast.  Keep those beds covered tightly so they will maintain a beneficial microenvironment under them.

I know that some of you did not get a chance to plant outside due to many reasons.  While it is unlikely we can plant, there may still be a chance.  When you get your bed set up with soil added, but have no plants,  place the row cover and plastic over the bed to keep the soil warm.  I will be watching to see if we get a tiny planting window and will let you know.  It is likely the only day this would work would be tomorrow, Tuesday the 29th, and only if the soil is pre-warmed. 

Inside under LED lights:

I think that planting under LED lights can be done, but only if you are able to take the plants home over Christmas break.  Hopefully everyones plants came through the long break ok.  If you have questions, please email me, and send me pics as well.

I keep my bok choy about 4 or so inches under the lights. Up to 6 inches away is OK as well. Those are some pretty powerful lights for growing greens.

 

This is bottom watering technique. The pots you have (I have six packs) are placed in an inch or so of water (with fertilizer if needed) for a half hour or so to take up water from the bottom. This fully hydrates all the soil in the pot. After a half an hour or so, take the pots out of the water, drain the water our of the bottom tray and place the spacer tray and pots back in the main tray to drain. As your plants grow,  they may need watered more often.  I need to water mine every three days now.  For the two inch pots, you probably need to water at least 1-2 times per week.

Inside in the Aerogarden:

How did everyone’s hydroponic units do over break?  Hopefully they came through fine and you have had a bunch of growth.

The Aerogarden website has a tremendous amount of content to assist with maintenance of the units, troubleshooting problems, or how to take care of the plants in the system.  CHECK IT OUT if you are having problems.

First up a weather report to get us through the Thanksgiving holiday weekend:

It was 70 degrees just last week but we have cold weather for quite a bit. I do not see a window to pop the top and check plants for a little while.

Outside in the raised beds:

I have been getting questions about what can still be planted outside.  We are likely done with planting in the raised beds. (See Below for a potential!)  Many folks have stated that they did not get good germination.  The warmer than normal weather made germination tricky unless the beds were watered daily until sprouting.  The heavy rain we had the other day may cause some delayed germination under cover that we will find when we are able to pop off the covers.  Make sure that when we get to the cold weather you do not uncover your beds on a cold day so that you do not shock your seedlings.  It should be above 45 degrees minimum to pop the top and it is better done around the middle of the day so you can re-cover, and build heat back up for the overnight lows.

Inside under LED lights:

I think that planting under LED lights can be done, but only if you are able to take the plants home over Christmas break.  With the 9 day break coming up,  if you have plants in your rooms under lights, the ideal situation would be to take them on a little field trip back to your house so you can keep an eye on them.  If you cannot take plants home over the upcoming Thanksgiving break then I recommend that you bottom water them with one to two inches of water in the bottom most tray. Take them out of the top spacer tray,  put them in the bottom tray with 1-2 inches of water.  Leave them in the water in the bottom tray until you return from break. They will slowly take up the water over the break and hopefully if nothing goes wrong, they will be growing and much bigger when you return. Consider adding fertilizer to the water as well due to the long length of time away.  And enjoy the holiday break!!

This is bottom watering technique. The pots you have (I have six packs) are placed in an inch or so of water (with fertilizer if needed) for a half hour or so to take up water from the bottom. This fully hydrates all the soil in the pot. After a half an hour or so, take the pots out of the water, drain the water our of the bottom tray and place the spacer tray and pots back in the main tray to drain.

For the upcoming break, I would add even more water to the tray than this. This tray has about a half inch of water, I would add at least one inch to one and a half inch of water for a 9 day break. If you can check the plants over break that would be even better.

Inside in the Aerogarden:

With the long holiday break upcoming we are getting questions regarding how to maintain the systems.  Ideally you would take them home with you.  They travel very well.  I place mine in a brownie pan or similar to catch any tiny spills then bring them back the same way.  If you want to leave your units at the schools, I am not sure they can do OK with no water for the 9 day break from 11/19 to 11/27.  I think they would need a mid-break check and water add.  Make sure to add the fertilizer as needed as well.  If you absolutely have to leave them alone for 9 days make sure to add the water to the line,  have the caps secured over the open holes, and have the timer good.  Add fertilizer if it will need added while you are gone.
